manu@localhost:~/gcc/gcc/c-family$ grep -C 3 "attempt to take address of" *.c
c-common.c- t = TREE_OPERAND (expr, 1);
c-common.c- if (DECL_C_BIT_FIELD (t))
c-common.c- {
c-common.c: error ("attempt to take address of bit-field structure "
c-common.c- "member %qD", t);
c-common.c- return error_mark_node;
c-common.c- }
error() uses "input_location" and that may point to anything. You need to use
error_at(), with the proper location of the second operand. (I'm not sure if
the second operand always have a proper location. If not, this then depends on
PR43486)
